8 Claims. 1

The invention relates to a new and improved sliding window for dwellings and other buildings.

One object of the invention is to provide a-comparatively simple and inexpensive construction in which all parts may be easily constructed.

Another object is to provide a novel construction which permits the slidable closure to slide into the space, provided by the usual iurring strips, between the building wall and the inner wall (of lath and plaster, or wallboard) secured,

to said furring strips.

A further object is to make novel provision for so mounting the slidable closures that they may be easily installed after the building is practically completed, and may later be readily removed for cleaning or for replacing any which may be broken.

A still further object is to provide a novel construction in which each slidable closure consists of a pane of glass provided at its lower edge with a shoe to engage a guide rail, no sash being required.

Yet another object is to provide a slidable window which may be easily and tightly screened.

With the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Figure 1 is .an inner'side ken away.

Fig, 2 is an outer side elevation with parts of the screen wire broken away.

Fig. 3is an enlarged vertical section on line 3-3 of Fig. 1.

Fig. 4 is a fragmentary horizontal section on line 4-4 of Fig. 1.

Fig. 5 is a. fragmentary vertical section on line 5-5 of Fig. 3.

Fig. 6 is an enlarged horizontal section on line 6-6 of Fig. 5.

Fig. 7 is a fragmentary perspective view showing more particularly the manner of insertin or removing one of the closure-abutting posts.

Fig. 8 is a detail vertical section on line 8-8 elevation, partly broof Fig. 1 with the closures removed.

Fig. 9 is a fragmentary perspective view show- .ing part of one of the slidable closures.

A preferred construction has been illustrated and will be specifically described, with the understanding, however, that within the scope of the invention as claimed, variations may be made,

The frame of the window embodies a sill structure ID. a crown structure II, and stile structures 42. The sill structure I!) comprisesan outer sill l3 and an inner sill or stool M; the crown structure H includes an outer crown bar I5 and an inner crown bar 16, spaced apart; and each stile structure I2 includes an outer stile ll and an inner stile l8, spaced apart.

Secured upon the innersill or stooll' l is a lower rail l9 which extends snugly between the outer stiles l1 and the inner stiles l8. 'Theend portions of this rail 19 projectbeyond the stile structures l2 to lie against the inner side of a building wall 20. Also secured uponthe inner sill or stool l4 and secured against the rail l9, are an outer bar 2| and an inner bar 22; said outer bar 2| extending from one of the outer stiles I! to the other, while said inner bar 22 extends from one of the inner stiles [-8 to the other.

Secured between and in'contact with the outer and inner crown bars l5 and I6, is an upper rail 23, the ends of which project beyond the stiles to lie against the innerside of the wall 20. This rail 23 is shown projecting downwardly beyond the outer crown bar l5, and the outer side of its downwardly projecting portion lies against a bar 24 secured to the lower side of said outer'crown bar l5, said bar 24 extending from one of the outer stiles l1 to the other.

Two intermediate rails 25 and '26 are shown, although there may be more than two, or only one, according to the size of the window. These rails 25 and 26 extend snugly between the outer stiles I1 and the inner stiles l8 and their ends project "beyond the stiles to lie against the inner side of the wall 20. Outer bars 21 and 28 are secured against the outer sides of the rails Hand 26, respectively, and extend from one of the outer stiles l'l to the other; and inner bars 29 and 30 are secured against the inner sides of said rails 25 and 26 and extend from one of the inner stiles I8 to the other.

One central post 3'! extends from the bar 24 to the bar 21 and is secured thereto; a second central post 32 extends from said bar 21 to bar 28 and is secured to them; and a third central post 33 extends from said bar 28 to the bar 2| and is secured to these bars.

Outer stop strips 34 are secured-to the inner 36 may besecured tothem. Suitable screen 39, said removable posts 42 resting on the sub;

jacent rails 25, 26 and 19 where the ridges 40 are cut away, at 4|. These removable posts have vertical grooves 43; the upper ends of these grooves communicate with the grooves 38; and

4 illustrated for securing the various frame parts together but other adequate fastening means could of course be employed. Moreover, it is of course possible to construct the frame in such a way that fasteners such as nails will not be necessary.

I claim: 1. In a window, a frame having opposed side members, an upper and a lower rail extending from one of said side members to the other, said side members each having a vertical slot through V which said rails extend, the lower edge of said the lower ends of said grooves receive the ridges 40. The posts 42 are thus normally held in place but sufficient space is provided over each post to allow it to be lifted from engagement with the .ridge 4B, permitting easy removal of the post.

To aid, the upper outer corner of each post 42 is preferably rounded oif as shown at 44.

Closures are slidably engaged with the various rails and extend slidably through the slots 45 between the stop strips 34 and 35. Each of these closures preferably consists of a glass pane 46 having a grooved shoe 41 on its lower edge. The upper edge of each pane 46 fits slidably in one of the grooves 38, the grooved shoe 41 engages one of the ridges 48, and the inner end of each pane is receivable in one of the grooves 43. A weather strip 48 (Fig. 4) maybe provided in the inner edge of each stop strip 34 and a weather seal 49 may be secured to the outer end of each shoe 41 to prevent entrance of rain and cold air through the slots 45. Also, if desired, the grooves '38 and 43 could well be lined with felt orthe like. The strip 48 not only forms a weather seal but each time the pane 46 is opened or closed, said pane is wiped by said strip, tending to keep the pane clean. I

When any one of the removable posts 42 is removed, either of the pans 45 cooperable with it may he slid inwardly 'sufficiently to clear. the slot 45, whereupon said panemay be lifted to free the shoe 41 from engagement with the ridge 4!]. Then, the pane'may be tilted to an inclined position and removed, forcleaning or to permit replacing of a damaged pane. It will also be clear that all of the panes may beleft out of the frame until the building is about completed, and that they may then be easily installed. r

The frame structure of the window constitutes 12. single unit around which the wall is built,

with the projecting ends of the rails 23, 25, 26 and i9 lying against the inner side of saidwall. These rails are of'substantially the same thickness as the conventional furring strips 5i!v and'will thus effectively aid in forming pockets between the wall 26 and the inner wall 5| when the latter is secured to said furring strips. Into these pockets, the panes or closures are slidabla, The inner wall 5! may abut and be flush with the inner crown bar It and the inner stiles l8, and suitable trim moulding 52 may be secured to said parts I6 and la; The wall 5i may also abut the lower side of the inner sill l4-to which trim moulding 53 may be secured.

From the foregoing, it will be seen that a novel and desirable window construction has been provided, and while preferences have been disclosed,

attention is again invited to the possibility of making variations within the scope of the invention as claimed. Suitably located nails have been upper rail being formed with a longitudinal groove being disposed centrally between the ends of said upper rail, the upper edge of said lower rail being formed with a longitudinal ridge the central portion of which is removed under said socket, a central post resting on the central portion of said lower rail and having its upper end seated in and upwardly slidable in said socket'of said upper rail, said post having vertical grooves which communicate at their upper ends with said groove of said upper rail, said ridge of said lower rail being seated in the lower ends of said vertical grooves of said post, two closures extending slidably through the aforesaid slots respectively and having their upper edges slidably received in the groove of said upper rail, the lower edges of said closures having grooves slidably engaging said ridge of said lower rail, the inner ends of said closures being receivable in said grooves of said post when said closures are slid to closed position; said post being upwardly disengageable from said ridge of said lower rail, to permit post removal, when said closures are slid from the grooves of said post; said closures being upwardly disengageable from said ridge of said lower track to permit closure removal when said closures are slid from said slots after removal of said post,
